Usability of a Digital Registry to Promote Secondary Prevention for Peripheral Artery Disease Patients

Abstract

Objective: To evaluate usability of a quality improvement tool that promotes guideline-based care for patients with peripheral arterial disease (PAD). Patients and Methods: The study was conducted from July 19, 2018, to August 21, 2019. We compared the usability of a PAD cohort knowledge solution (CKS) with standard management supported by an electronic health record (EHR). Two scenarios were developed for usability evaluation; the first for the PAD-CKS while the second evaluated standard EHR workflow. Providers were asked to provide opinions about the PAD-CKS tool and to generate a System Usability Scale (SUS) score. Metrics analyzed included time required, number of mouse clicks, and number of keystrokes. Results: Usability evaluations were completed by 11 providers. SUS for the PAD-CKS was excellent at 89.6. Time required to complete 21 tasks in the CKS was 4 minutes compared with 12 minutes for standard EHR workflow (median, P ¼ .002). Completion of CKS tasks required 34 clicks compared with 148 clicks for the EHR (median, P ¼ .002). Keystrokes for CKS task completion was 8 compared with 72 for EHR (median, P ¼ .004). Providers indicated that overall they found the tool easy to use and the PAD mortality risk score useful. Conclusions: Usability evaluation of the PAD-CKS tool demonstrated time savings, a high SUS score, and a reduction of mouse clicks and keystrokes for task completion compared to standard workflow using the EHR. Provider feedback regarding the strengths and weaknesses also created opportunities for iterative improvement of the PAD-CKS tool.

Outpatient management of patients with peripheral artery disease by cardiologists or surgeons: influence on the prognosis and prevalence of surgical interventions

“…Inefficient treatment of PAD patients can contribute to high preventable cardiovascular morbidity and mortality. Accordingly, solutions to improve the rate of optimal management for PAD patients and in-crease their adherence to the treatment are sought for [12][13][14]. The complexity of the situation lies in the fact that observing patients with PAD requires solving multiple problems: first, indications for and type of revascularizing interventions, and second, regardless of the need for revascularization, medication therapy and secondary prevention measures required to prevent the progression of the lower extremities arterial lesions.…”
